WILLIAM M. HOERLE, OF CLEVELAND, OHIO, ASSIGNOR TO THE PITTSBURGH BRASS COMPANY, OF ALLEGHENY CITY,

WICK-RAISER FOR LAMPS.

SPECIFICATION forming part of Letters Patent No. 435,357, dated August 26, 1890.

Application filed February 14, 1889. Serial No. 299,921. (No model.)

To all whom it may concern:

Be it known that I, WVILLIAM M. HOERLE, a citizen of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Wick-Raisers for Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

My invention relates to that class of lamps which are known as .Argand or centraldraft lamps; and the object is to provide a novel wick-raising device which may be easily caused to engage and disengage the wick.

To this end it consists in a construction and combination of parts herein described, and pointed out in the claim.

Referring to the drawings, Figure 1 is a central vertical sectional View of a lamp having my improvements applied thereto. Fig. 2 is a side View of the wick-fingers and a slotted plate which guides them. Fig. 3 is a horizontal sectional view of the wick-raising mechanism, taken on the line 3 3 in Fig. 1.

Similar letters represent corresponding parts in the several figures.

In the drawings,Arepresents the oil-fount, and B a cylindrical tube passing centrally through said fount, which serves both as a wick-tube and a draft-tube. C represents a tube which passes vertically through said fount and is soldered or otherwise secured to the walls thereof.

D represents a tube which passes through and revolves within the tube 0, where it is held by the two collars d d, which are secured to its ends. F represents a rod which passes up through said tube D, and which is then bent downward and passes into the fount A. That part of the rod F which passes within the tube D is provided with a spiral groove which engages with a spiral rib on the inner wall of said tube, so that by the revolution of said tube D the rod F is forced up or down, as the case may be. At the lower end of the tube D the collar d is in the form of a thumb-screw, whereby said tube may be easily revolved.

E represent fingers which are independently pivoted to the end of the rod F. Their free ends are curved so as to fit around the central draft-tube B, and small prongs e are provided on the ends of said fingers,whereby the wick is firmly grasped.

G represents a plate arranged vertically within the fountAbetween the rodF and the central draft-tube B. This plate is provided with a vertical slot, which is bifurcated near the top by means of the pointed tongue g, thereby forming two independent slots which lie at an angle to each other. The shanks e of the wick-fingers E pass through this slot, and by their engagement with the side walls thereof in their vertical movement they are prevented from becoming disengaged from the wick. \Vhen said fingers are moved up far enough, the point of the tongue g passes between them, thereby guiding the shank of one into'the slot on one side of said tongue and the shank of the other into the slot on the other side of the tongue, thereby spreading them and releasing the wick, which may then be easily removed and a new wick substituted whenever desired.

This wick-raising device may be usedin connection with a sliding sleeve placed around the central draft-tube, and either inside or outside of the wick-such as is commonly found in the central-draft lamps-and has this advantage over many of them-viz.,that it is not necessary to remove the wick-raising device when it is desired to change the wick. The device may also be used (and preferably is so used) without such sliding sleeve as shown in the drawings, the fingers themselves satisfactorily answering the purpose for which said sleeves are employed.

Having thus described my invention, what I claim as new, and desire to secure by Letters 0 Patent, is-

The combination of a cylindrical wick-tube,

a verticallymovable rod, and two curved wick-fingers pivotally connected with said rod, with a plate G, having a vertical slot, the 5 walls of which diverge at its upper end, and

a pointed finger g, which bifurcates said slot, substantially as shown,whereby the side walls of said slot hold the wick-fingers in position to engage with the wick, and the pointed fin- IOO ger g spreads them apart and thereby disengages the wick. WM. M. HOERLE.
